Chronic Cancer Risk CREG from the EPA
Numerous studies have shown a correlation between ethylene oxide (EtO) exposure and increased cancer risks. Human occupational studies have revealed elevated cases of lymphoid cancer and breast cancer among female workers. Animal studies have further confirmed the carcinogenic properties of ethylene oxide, demonstrating its potential to cause lymphoid cancer and tumors in the brain, lung, connective tissue, uterus, and mammary gland through inhalation exposure. The Environmental Protection Agency (EPA) has concluded that ethylene oxide is carcinogenic to humans via inhalation and supports a mutagenic mode of action for its toxicity. The EPA utilizes mathematical models to estimate cancer probabilities associated with specific air concentrations of EtO. For both lymphoid cancer and breast cancer in females, the inhalation unit cancer risk estimate for ethylene oxide is calculated at 3 × 10-3 per µg/m3 (6 × 10-3 per ppb). Considering the mode of action, if an individual were to continuously breathe air containing an average concentration of 2 × 10-4 µg/m3 (1 × 10-4 ppb) of ethylene oxide throughout their lifetime, the theoretical increased chance of developing cancer would be no more than one in a million. Similarly, continuous inhalation of air with concentrations of 2 × 10-3 µg/m3 (1 × 10-3 ppb) or 2 × 10-2 µg/m3 (1 × 10-2 ppb) of ethylene oxide would result in not greater than a one-in-a-hundred thousand or a one-in-ten thousand increased chance of developing cancer, respectively. These findings highlight the significance of considering ethylene oxide exposure levels and their potential impacts on cancer development.
